Description

Technical Field

[0001] The utility model relates to the technical field of luggage, in particular to a folding trolley bag. Background Art

[0002] A trolley bag refers to a bag with a pull rod, which combines the softness of the bag and the labor-saving of the pull rod. The pull rod is arranged on the bottom surface of the bag and can be telescoped along the length direction of the bottom surface. After the pull rod is retracted, it is convenient to pull out the handle again. The handle of the pull rod is located in the edge area of the bottom surface of the bag, so as to realize the retraction and storage of the pull rod. In addition, a whole hard board is arranged on the bottom surface of the bag, and the hard board and the pull rod work together to increase the rigidity of the bottom surface of the bag, so as to maintain the shape of the trolley bag and improve its storage strength. During the storage and transportation of the trolley bag (not when the user uses it as a travel bag), since its bottom surface is rigid and straight and cannot be folded, the size of its bottom surface has a great influence on the storage size of the trolley bag, which is not conducive to the storage and transportation of the trolley bag. Summary of the Invention

[0003] The purpose of the utility model is to provide a folding trolley bag to solve the problem that the flat and non-foldable bottom surface of the existing trolley bag is not conducive to the storage and transportation of the trolley bag.

[0004] To achieve the above purpose, the technical solution of the utility model is: a folding trolley bag, including a bag and a pull rod assembly arranged at the bottom of the bag. A main hard board structure and at least one auxiliary hard board structure are arranged at the bottom of the bag. The pull rod assembly is a telescopic rod structure, and the pull rod assembly has a retracted state and a stretched state. The retracted pull rod assembly is correspondingly arranged with the main hard board structure, and there is a gap between the main hard board structure and the adjacent auxiliary hard board structure, so that a foldable structure is formed at the bottom of the bag.

[0005] In one embodiment, the pull rod assembly includes a fixed end and a telescopic end. The main hard board structure and the auxiliary hard board structure are arranged at intervals along the telescopic direction of the pull rod assembly. The fixed end is arranged at one end of the main hard board structure away from the auxiliary hard board structure, and the telescopic end is arranged at one end of the main hard board structure close to the auxiliary hard board structure. The length of the retracted pull rod assembly is less than that of the main hard board structure.

[0006] In one embodiment, the bottom of the bag is a multi-layer cloth structure, and the pull rod assembly is arranged in the multi-layer cloth structure so that the pull rod assembly is hidden. The pull rod assembly includes a fixed end and a telescopic end. A pull rod opening is arranged at the edge of the bag close to the telescopic end, and the pull rod opening is used for the pull rod assembly to pass through the pull rod opening for telescoping.

[0007] In one embodiment, the bag is provided with an outer cover at the opening of the pull rod, and the outer cover is used to selectively cover the opening of the pull rod.

[0008] In one embodiment, the first edge of the outer cover is fixedly connected to the main body of the bag, and the second edge of the outer cover is connected to the main body of the bag by a zipper, so that the outer cover can selectively cover the opening of the pull rod by means of the zipper.

[0009] In one embodiment, the pull rod assembly includes a fixed rod group and a telescopic rod group. The telescopic rod group includes a first telescopic rod and a second telescopic rod arranged at intervals. Handles are provided at the ends of the first telescopic rod and the second telescopic rod. An inner cover is also provided at the opening of the pull rod. The inner cover is configured as a selectively openable and closable structure, and the inner cover is formed between the first telescopic rod and the second telescopic rod of the pull rod assembly.

[0010] In one embodiment, the inner cover includes a first sheet body and a second sheet body. One edge of the first sheet body and the second sheet body is respectively fixedly connected to the main body of the bag, and the opposite edges of the first sheet body and the second sheet body are detachably connected by a magic tape, so that the inner cover is formed into a selectively openable and closable structure.

[0011] In one embodiment, the bag includes a storage cavity. The multi-layer cloth structure includes an inner layer, and the inner layer is used to form the side wall of the storage cavity. The inner layer is provided with an opening and closing structure, and at least a part of the pull rod assembly is exposed by opening the inner layer by means of the opening and closing structure.

[0012] The beneficial effect of the present utility model is that: the present utility model divides the traditional whole hard board at the bottom of the pull rod bag into a main hard board structure and a secondary hard board structure, so that the bottom of the pull rod bag is formed into a foldable structure, and the length after the pull rod assembly is retracted is shortened to correspond to the main hard board structure, preventing the pull rod assembly from hindering the folding of the bottom of the pull rod bag at the gap between the main hard board structure and the secondary hard board structure, so that the bottom of the pull rod bag can be folded to reduce the storage size of the pull rod bag, facilitating the storage and transportation of the pull rod bag.

Detailed implementation manners

[0021] To further illustrate each embodiment, the present utility model provides drawings. These drawings are a part of the disclosure of the present utility model, which are mainly used to illustrate the embodiments and can be used to explain the operating principle of the embodiments in conjunction with the relevant descriptions in the specification. With reference to these contents, those of ordinary skill in the art should be able to understand other possible implementation manners and the advantages of the present utility model. The components in the drawings are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0022] Refer to Figures 1 to 4 as shown, the present utility model discloses a folding drawbar bag, which includes a bag 1 and a drawbar assembly 2 arranged at the bottom of the bag 1. The bottom of the bag 1 is provided with a main hard board structure 11 and an auxiliary hard board structure 12( Figure 2 the dotted frames in represent the main hard board structure 11 and the auxiliary hard board structure 12 respectively), the drawbar assembly 2 is a telescopic rod structure, the drawbar assembly 2 has a contracted state and a stretched state, the drawbar assembly 2 in the contracted state is correspondingly arranged with the main hard board structure 11, and there is a gap between the main hard board structure 11 and the adjacent auxiliary hard board structure 12 so that a foldable structure is formed at the bottom of the bag 1.

[0023] The bag 1 is a soft structure made of fabric. Except for the handle assembly 2, only the bottom of the bag 1 is a rigid structure. Therefore, the other parts of the bag 1 except the bottom can be folded or squeezed, which has little impact on the size of the folded trolley bag. The utility model changes the structure of the whole rigid plate at the bottom of the traditional trolley bag, and divides the rigid structure at the bottom of the trolley bag into a main rigid plate structure 11 and a secondary rigid plate structure 12, so that the bottom of the trolley bag forms a foldable structure, and the length of the handle assembly 2 after contraction is shortened to correspond to the main rigid plate structure, preventing the handle assembly 2 from hindering the folding of the bottom of the trolley bag at the gap between the main rigid plate structure 11 and the secondary rigid plate structure 12, so that the bottom of the trolley bag can be folded in the state shown in Figure 3 to reduce the storage size of the trolley bag, which is convenient for the storage and transportation of the trolley bag.

[0024] The handle assembly 2 includes a fixed end and a telescopic end. The telescopic end is provided with a handle 21. The main rigid plate structure 11 and the secondary rigid plate structure 12 are arranged at intervals along the telescopic direction of the handle assembly 2. The fixed end is arranged at one end of the main rigid plate structure 11 far from the secondary rigid plate structure 12, and the telescopic end is arranged at one end of the main rigid plate structure 11 close to the secondary rigid plate structure 1. The length of the handle assembly 1 in the contracted state is less than that of the main rigid plate structure 11, so as to ensure that the telescopic end of the handle assembly 2 in the contracted state does not extend beyond the main rigid plate structure 11, and further prevent the handle assembly 2 from hindering the folding of the bottom of the trolley bag at the gap between the main rigid plate structure 11 and the secondary rigid plate structure 12.

[0025] The bottom of the bag 1 is a multi-layer cloth structure. The handle assembly 2 is arranged in the multi-layer cloth structure so that the handle assembly is hidden. Except for the handle assembly 2, the main rigid plate structure 11 and the secondary rigid plate structure 12 are also arranged in the multi-layer cloth structure. Therefore, the main rigid plate structure and the secondary rigid plate structure are also hidden inside the bag 1. The hidden design of the handle assembly 2, the main rigid plate structure 11 and the secondary rigid plate structure 12 makes the whole trolley bag more beautiful. However, since the handle assembly 2 does not extend beyond the main rigid plate structure 11 in the contracted state, the handle assembly 2 is restricted inside the bag 1. Therefore, a handle opening 13 is provided at the edge of the bag 1 close to the telescopic end for the handle assembly 2 to pass through the handle opening 13 to achieve telescoping.

[0026] The bag 1 is provided with an outer cover 14 at the opening 13 of the pull rod. The outer cover 14 is used to selectively cover the opening 13 of the pull rod. Specifically, the first edge of the outer cover 14 is fixedly connected to the main body 10 of the bag 1, and the second edge of the outer cover 14 is connected to the main body 10 of the bag 1 through a zipper 141. Thus, the outer cover 14 can selectively cover the opening 13 of the pull rod by means of the zipper. When the zipper of the outer cover 14 is opened, the opening 13 of the pull rod is exposed, enabling the pull rod assembly 2 to smoothly pass through the opening 13 of the pull rod and stretch. When the zipper of the outer cover 14 is closed, the opening 13 of the pull rod can be sealed, thereby forming a dust-proof structure and making the overall pull rod bag more beautiful. In this embodiment, the outer cover 14 selectively covers the opening 13 of the pull rod through a zipper, with a simple structure and easy operation. In other embodiments, the outer cover 14 can also selectively cover the opening 13 of the pull rod through structures such as buckles or Velcro.

[0027] The pull rod assembly 2 includes a fixed rod group and a telescopic rod group. The telescopic rod group includes a first telescopic rod 22 and a second telescopic rod 23 arranged at intervals. The ends of the first telescopic rod 22 and the second telescopic rod 23 are provided with a handle 21. An inner cover 15 is also provided at the opening 13 of the pull rod. The inner cover 15 is configured as a selectively openable and closable structure and is formed between the first telescopic rod 22 and the second telescopic rod 23 of the pull rod assembly 2. Specifically, the inner cover 15 includes a first sheet body and a second sheet body. One edge of the first sheet body and the second sheet body are respectively fixedly connected to the main body 10 of the bag 1, and the opposite edges of the first sheet body and the second sheet body are detachably connected through Velcro, so that the inner cover 15 is formed into a selectively openable and closable structure.

[0028] When the handle 21 of the pull rod assembly 2 needs to pass through the opening 13 of the pull rod, the inner cover 15 is opened so that the pull rod assembly 2 can stretch smoothly. When the pull rod assembly 2 is fully stretched, the inner cover 15 is closed, which can form a dust-proof structure for the accommodating cavity of the pull rod assembly and can also block the part of the pull rod assembly 2 located within the multi-layer cloth structure. When there are items in the bag (for example, when the pull rod bag is used as a travel bag or a luggage bag), it is not convenient to fully retract the pull rod assembly 2 because it is difficult to be stretched due to the obstruction of the items in the bag after being fully retracted, and the pull rod assembly 2 is not always in the fully stretched state. At this time, closing the inner cover 15 can block the handle 21 and prevent the pull rod assembly 2 from continuing to retract, facilitating pulling the handle 21 again to extend the pull rod assembly 2.

[0029] Among them, the fully stretched state of the pull rod assembly 2 means that the pull rod assembly 2 is stretched to the longest, and this state is mostly used when the user pulls the handle 21 of the pull rod assembly 2 to tow the pull rod bag.

[0030] The bag 1 includes a storage cavity 16. The multi-layer cloth structure includes an inner layer 160. The inner layer 160 is used to form the side wall of the storage cavity. The inner layer 160 is provided with an opening and closing structure 161. By means of the opening and closing structure 161, the inner layer is opened so that at least a part of the pull rod assembly 2 is exposed. Since the pull rod assembly 2 is contracted into the interior of the pull rod bag when the pull rod bag is folded, when the pull rod assembly 2 needs to be extended, it is difficult for the user to pull the handle 21 from the pull rod opening 13. The existence of the opening and closing structure 161 enables the user to easily access the handle 21, so as to extend the pull rod assembly 2 by a certain length, facilitating the user to pull the handle 21 from the pull rod opening 13.

[0031] In this embodiment, the opening and closing structure on the inner layer 160 is a zipper. In other embodiments, structures such as buckles or Velcro can be used instead of the zipper, or the overlapping of two pieces of cloth can be used instead of the zipper.

[0032] In addition, the bag 1 of this embodiment is further provided with a storage cavity 17. The storage cavity 17 is arranged on the side of the storage cavity 16 away from the bottom. The storage cavity 17 is a hollow cavity for storing items. Its specific structure and function are both prior arts and will not be elaborated here. In other embodiments, it is also feasible to combine the storage cavity 16 and the storage cavity 17 into a larger cavity for placing items.

[0033] There is one secondary rigid structure 12 in the above embodiment. In other embodiments, there can also be multiple secondary rigid structures 12, and the multiple secondary rigid structures 12 are spliced along the telescopic direction of the pull rod assembly 2, making the folding of the bottom of the bag simpler.

[0034] Although the present utility model is specifically shown and introduced in combination with the preferred implementation schemes, those skilled in the art should understand that the remaining unstated parts are prior arts, and any changes made to the present utility model in form and details without departing from the spirit and scope of the present utility model defined by the appended claims all fall within the protection scope of the present utility model.
